Samuel Lil’ Sam Walker, a 13-year-old African American boy, was killed on July 25, 2014 in a drive-by shooting on Chicago’s West Side near Lexington Street and California Avenue. He was shot in the head and torso and died at the scene; six other people were wounded. Samuel had been preparing to start at Manley High School that fall and family described him as a smart boy looking forward to high school.

Investigators noted Samuel was gang-affiliated, a detail said to complicate the case. No arrests have been made in connection with his murder. Six days after Samuel’s death, his father, 34-year-old Samuel Walker Sr., was shot multiple times in Humboldt Park and died; his killing was later the subject of a first-degree murder charge against Kortillious Gipson. Samuel Jr and his father were buried together.

Does anyone who knew Samuel or who was in that neighborhood on July 25, 2014 have information that could help bring answers in his case?
